Got a radiator

I obtained a small heater core for use as a radiator for the cooling system for the extruder and the high speed milling spindle. It measures about 9.5" x 6.375" x 2". I modified the heater core by cutting the ends off the tubes and fitting hose barbs to the inlet and outlet. I'm going to run coolant lines to the extruder and spindle using quick disconnect fittings so I can easily swap them. 

After reading multiple discussions on the CNC forum it looks like cooling fans probably will not be necessary since I really do not plan on using anything more than a 1.3kW maximum spindle. I still need to find an inexpensive pump...
